A private tool for investors. It lists founders found from public sources, grades them, and keeps your own outreach and deals in one place. Every account is individual. Anyone can sign up with a Google account.
Your email address and name, from Google sign-in or the address you set a password on. What you do on the site: votes on grades, contacts and deals you add, comments, files you upload, and the messages you import or send through the site. Sign-in times.
machinezero runs a shared AI that learns from how members use the site. On the Free plan, what you add and do on machinezero helps train it, and other members never see your name. On Private, nothing you add trains it.
Founder profiles come from public professional and academic sources and are shown only to signed-in members. A founder can ask for their entry to be removed at the address below.
machinezero never holds a LinkedIn password or session. The machinezero Connector extension links the site to the LinkedIn tab you are signed into. Only when you press Sync now does it read your recent conversations, and only when you press Send does it send the message you typed. It reads nothing on other sites and nothing in the background.
Imported conversations go to your own machinezero account over HTTPS and nowhere else. The extension keeps one thing on your machine: a short activity log with names and counts, never message text. It paces itself like a person, one message per click, and stops for 30 minutes if LinkedIn pushes back.
When you reply to a contact who only has an email address, the site opens a draft in your own mail app. It records the message only if you then mark it as sent. The site sends email itself only for password links and deals you share.
If you connect Gmail under Settings, machinezero can read your mailbox. It only searches for five kinds of mail: mail from the addresses and website domains of your own deals; mail you sent to those same addresses and domains; calendar invitations (Google Calendar and Calendly) so it knows who you meet with; mail from anyone whose subject reads like an investor update ("investor update", "monthly update", "Q3 update" and the like); and mail you label Radar. Emails from your deals are saved as updates on their deal, where only you can see them, not the people you share the deal with, and they and your replies to them appear in that founder's message thread, which is yours alone. A PDF attached to a founder's email is added to the files of that deal when the deal is yours; like a file you upload, anyone you share the deal with can see it. An investor-update email from a company on none of your deals is read by an AI model to decide whether it is a company reporting to its investors: if it is, it waits for you to keep that company or ignore it; if not, its text is deleted. From an invitation it keeps only who was invited, the event title, its time and its Google Meet link. Beyond that it only looks at mail that arrives after you connect, with one exception: when you connect, it looks back once over the two years before, only at emails people sent you with a PDF attached. A PDF from someone on one of your deals is added to that deal. Any other such email is read by an AI model to decide whether it is a startup pitching you; if it is, it becomes a deal with that deck, visible only to you under "From inbox" until you put it up for review, and if not, its text is deleted. If you also allow it on Google's screen, it reads your Google Calendar for the same reason it reads invitations, only events from the day before onward, and from each one it keeps only who is on it, the title, the time and the Google Meet link; and it sends an email from your Gmail when you press Send on an email in Messages, to that contact only, with the text you wrote. It never sends anything you did not send yourself, and never deletes or changes mail or calendar events. Google's access token is stored encrypted and is used only for these searches, that calendar read and the emails you send.
Each saved update is summarized, and a profile of each company is written from its updates (visible only to you), by an AI model that Metavision Labs runs to provide this feature. Gmail data is not used for advertising, is not sold, is not used to train machinezero's shared AI, and is not shared with anyone except as needed to provide this feature. Our use of information received from Google APIs follows the Google API Services User Data Policy, including the Limited Use requirements.
Saved updates are kept until you delete them. Delete any update from its deal, or ask us at the address below to delete all of them. Disconnect Gmail in Settings to stop access at once and have Google revoke our token. You can also remove machinezero from your Google account's security settings.
Reply drafts, deck memos and the writing rules under Voice are produced by an AI model run by Metavision Labs from the thread or file in question. A draft is never sent without a click.
Block an address, a domain, a LinkedIn profile or a conversation under Settings, Privacy. What the site holds from it is deleted and never imported again.
Cloudflare hosts the site, the database and the files. Google handles sign-in. Resend delivers the emails. Microsoft Clarity records how the site is used: where people click and scroll, and how long they stay on each page. Every word on the page is hidden from it, so it never sees your deals, contacts or mail. Nothing is sold or shared with anyone else.
One signed cookie keeps you signed in. Microsoft Clarity sets two more to tell one visit from the next.
Ask for a copy of what we hold, a correction, or deletion at the address below. Your contacts, threads and deals are yours alone; no other member sees them unless you share a deal with them.
